Saturn's moon Titan continued to surprise scientists during a flyby that took Cassini into regions previously unexplored by radar.
Two NASA satellites were launched Friday from Vandenberg Air Force Base, Calif., on missions to reveal the inner secrets of clouds and aerosols, tiny particles suspended in the air.
NASA's Phoenix Mars Lander, the next mission to the surface of Mars, is beginning a new phase in preparation for a launch in August 2007.
A pair of dancing galaxies appears dressed for a cosmic masquerade in a new image from NASA's Spitzer Space Telescope.
A globe-spanning constellation of six weather and climate research satellites based on a novel application of NASA-developed technology is set to launch from Vandenberg Air Force Base, Calif., Friday, April 14.
Researchers today released the first Mars images from two of the three science cameras on NASA's Mars Reconnaissance Orbiter. Images taken by the orbiter's Context Camera and Mars Color Imager during the first tests of those instruments at Mars confirm the performance capability of the cameras.
NASA's Mars rover Spirit has reached a safe site for the Martian winter, while its twin, Opportunity, is making fast progress toward a destination of its own.
NASA has signed an agreement with other U.S. and international agencies to launch the Ocean Surface Topography Mission in 2008.
The Cassini-Huygens mission team, which has captured the most detailed views ever of Saturn and its myriad of moons, was honored with an Aerospace Laurel award by the editors of Aviation Week & Space Technology magazine.
NASA has awarded a subcontract to Northrop Grumman Space Technology in Redondo Beach, Calif., to develop an ultra-cold mechanical helium cryocooler for the Mid-Infrared Instrument on the James Webb Space Telescope.
NASA's Spitzer Space Telescope has uncovered new evidence that planets might rise up out of a dead star's ashes.
NASA's Mars Reconnaissance Orbiter yesterday began a crucial six-month campaign to gradually shrink its orbit into the best geometry for the mission's science work.
Scientists with NASA's Cassini mission have found evidence that a new class of small moonlets resides within Saturn's rings. There may be as many as 10 million of these objects within one of Saturn's rings alone.
It may not be the final four, but it's definitely an exciting time for some Southern California high school students who won a regional game of robotics basketball.
The first test images of Mars from NASA's newest spacecraft provide a tantalizing preview of what the orbiter will reveal when its main science mission begins next fall.
Astronomers using NASA's Spitzer Space Telescope have conducted a cosmic safari to seek out a rare galactic species. Ultimately, the expedition resulted in quite a catch - the most distant galaxy cluster ever seen, located 9 billion light-years away.
Marine scientists have figured out a way to see through the ocean's surface and detect what's below, with the help of satellites.
NASA's long-lived Mars rovers demand lots of care as they age and the Martian winter approaches.
Where there's smoke, there's fire - even in outer space.
Solar System Ambassadors are JPL-trained volunteers who share the wonders of space exploration with their communities. Each ambassador agrees to conduct at least four public outreach events during the year.
